CUTTER-BAR.

SPECIFICATION forming part 0f Letters Patent No. 697,050, dated April 8, 1902.

Application tiled October 10, 1901. Serial No. 78,172. (No model.)

T0 all whom, it may concern.-

Be it known that I, DAVID E. WHITE, a citizen of the United States, residing at Winchester, in the county of Jefferson and State of Kansas, have invented a new and useful Cutter-Bar, of which the following is a speci tication.

This invention relates to cutting apparatus for mowing-machines and the like, and has for its object to provide an improved cutterbar wherein the bar is materially stiifened and strengthened and the cutting-blades are connected thereto in a simple and improved manner, so as-to obviate as much as possible the breaking of the cutters and to facilitate their connection to the bar. It is also designed to arrange the cutter-plates so as to mutually brace each other and also to present a'smooth upper surface which is entirely free from projections, so that the bar may work smoothly in the guide thereof.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the ac-l companying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective View of a portion of a cutter-bar embodying the present invention. Fig. 2 is a longitudinal sectional view thereof. Figs. 3 and are cross-sectional views on the lines 3 3 and 4 et of Fig. 2, respectively. Fig. 5 is a detail perspective view of one of the cutter-blades.

Like characters of reference designate corresponding partsin all the figures of the drawings.

In carrying out the present invention there is provided the usual bar l, to which the two sets of teeth 2 and 3 are connected, each tooth having a substantially triangular projection provided with sharp beveled cutting edges in the usual manner and one set of teeth being of the ordinary type. Each of the other alternate teeth 2 have extended back portions, which are folded over against the under sides thereof, as indicated at 4:, so as to produce a` thickened rib or back edge portion, the folded part being projected at opposite ends to form the attaching ears or projections 5, each of which is provided with a perforation 6, and a similar perforation 7 is formed in the intermediate portion of the folded back edge of the blade. These blades are applied directly to the upper side of the cutter-bar, with the outer ends of adjacent ears 5 abutting, so as to space the blades at a proper distance to receive one of the ordinary blades 3, which is fitted flat against the abutted ears and secured to the bar by means of rivets or other suitable fastenings 8 passed through the blade 3, the perforatious 6 in the underlying ears, and the cutter-bar, whereby these fastenings serve to hold the blade 3 and portions of the two adjacent blades 2 to the cutter-bar, and another rivet 9 is set through the intermediate perforations 7 of the blade 2, so as to connect said intermediate portion to the bar.

It will here be noted that the folded portion of the blade 2 presents a double thickness, so that when the blade 3 is fitted in place and rests upon the ears 5 it is flush with the upper faces of the adjacent blades, thereby to obviate `projections and to provide asmooth iush upper surface for the cutter-bar.

From the foregoing description it is apparent that the blades are connected to the cutter-bar in a simple and durable manner, and

the blades are arranged to mutually brace each other, so as to take up strain and obviate breaking of the blades. Moreover, should any of the blades become broken they may be as readily removed and replaced asin the ordinary form of cutter-bar.

Vhat I claim is- 1. The combination with a cutter-bar, of two sets of cutter-blades, each memberof one VVset having oppositely-directed lateral attaching-ears applied to the bar, the upper faces of the ears being below the upper faces of the blades, said blades being spaced at predetermined intervals to receive the members of the other set of cutter-blades, the latter resting upon the opposite ears of adjacent blades and flush with the upper faces thereof.

2. A cutter-bar, havin a pair of cutterblades which are provided with opposite lat- IOO / plied flat against the opposite ears ofthe firstmentioned pair ofblades,and fastenings piercing said blade, the ears and the bar, the upper faces of all of the blades being. ush.

3. A cutter-bar having tv vo sets of cutterblades, each member of one set having its .rear end portion folded upon the under side thereof and projected at opposite sides of the Y' blade to form attaching-ears, and the membersof the other set of blades being applied r1.o the opposite ears of adjacent blades, the upper faces of all ofthe blades being flush, and

fastenings piercing the bar, the ears and the blades applied thereto.

4. As a new article of manufacture, a cutv ter-blade having its rear edge portion folded over u pon-the under side thereof and also projectedat opposite edges of the blade to form attaching-ears- 5. As a new article of manufacture, a cutter-blade Which is substantially triangular in shape and has its opposite side edges beveled to form cutting edges, the rear edge portion of the blade being folded over upon the under side thereof and also projected at opposite edges to form attaching-ears, each of the latter being provided with a perforation for the reception of a fastening, and the folded portion being provided With an intermediate perforation.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in the presence of tWo Witnesses.

DAVID E. WHITE.
